Advance Wars

If you're already quite good at Advance Wars and you want an extra challenge,
try begining an Advance Campaign. To get it, you need to 1st buy the "Advance
Campaign" under Battle Maps (this will become available either after completing
the Campaign Mode once). Once you have bought it (it only costs a buck), start a
new Campaign while holding down the Select button. The words Advance Campaign
will appear in the upper left corner, the computer AI will be tougher and some
of the units in the following missions will be stronger. For example, instead of
regular tanks, you often face MD Tanks, your opponent has more units, and you
less, and so on. But in return, you will get much more cash for winning
missions.

After you have finished the Field Training missions (and in the course opened up the War Room, Campaign, Design Maps and Stats features), go back into Field Training. A very short tutorial called Special Intel is now available that gives you extra gameplay tips.

Beating the regular campaign will unlock Olaf as a playable CO in Vs. and Link
Mode, but you can also get some of the other COs as well. The only problem is
that you have to pay for them and certain conditions have to be met to unlock
them. Check the Battle Maps room after you win the Campaign mode -- and Hachi
will offer COs for sale (for 50 coins, so save up). Here are the conditions that
have to be met to unlock certain COs:
Olaf: Unlocked after beating Campaign Mode
Grit: Beat Campaign Mode and use Max in Mission 4. Buy from Hachi for 50
coins.
Eagle: Beat Campaign Mode and use Sami for missions 15, 16, 17, 18, then beat
secret mission 22. Buy from Hachi for 50 coins.
Kanbei: Beat Campaign Mode. Buy from Hachi for 50 coins.
Drake: Beat Campaign Mode. Use Andy for missions 15, 16, 17, and 18. Buy from
Hachi for 50 coins.
Sonja: Beat Campaign Mode. Beat Mission 9 in 8 days (or less), Mission 10 in
10 days, Mission 11 in 12 days, then win the secret missions 12, 13, and 14.
You can then buy Sonja from Hachi for 50 coins.
Sturm: Beat Campaign Mode and unlock all other COs. You can then buy Sturm
from Hachi.
